WebAnatomy & Function of the Dendritic Spines. Dendritic spines are usually described by a bulbous head, connected via a thin cytoplasmic protrusion (neck) on the parent dendrite. Their length is maximum 2 μm and the spine head volumes can be 0.01 µm 3 to 0.8 µm 3. There can be thousands of dendritic spines on a neuron. http://pressbooks-dev.oer.hawaii.edu/anatomyandphysiology/chapter/basic-structure-and-function-of-the-nervous-system/
